Abstract
The reconstruction of a furnace with a rolling hearth for the heat treatment of welded metal structures is described. The primary heating system based on twelve high-speed recuperative burners is supplemented by a recirculation system for the exhaust gas, which is heated in a portable chamber. That ensures uniform temperature distribution in the furnace’s working chamber, to within ±10°C. The introduction and debugging of the furnace is considered.
